HVAC Troubleshooting in Phoenix, AZ

Like most modern equipment, your HVAC unit is a sophisticated system with many intricate components. Unfortunately, it can develop faults due to wear and tear or poor installation, among other factors, but you can troubleshoot your system by following these tips.

Reset Your HVAC System

If your HVAC system is not operational, you can try running a reset. Modern models have complex circuitry, and you can solve many issues by simply rebooting your system. The purpose of the reset button is to prevent overheating and explosions. If there has been a power outage and your HVAC unit is not working, resetting it is one way to resolve the issue.

You may also use the reset if your air conditioning unit is blowing warm air. Sometimes the issue arises due to a thermostat glitch. Restarting the equipment can often correct the error, restoring the cooling function of your HVAC system.

Start by switching off your unit at the shut-off panel. Next, turn off the power at the circuit breaker. Locate the reset button, which is typically red. Hold it for a few seconds and switch it back on. Your HVAC system should start.

Troubleshoot the Thermostat Before Other Parts

When troubleshooting complex systems such as your HVAC unit, you should rule out the simplest and most obvious cause of the fault. You can start by checking the power supply and resetting your system.

The thermostat is another component of the system you should rule out before making any conclusions. An incorrect setting or device malfunction can cause noticeable changes in performance.

One of the problems your thermostat may cause is frequent cycling. Check the thermostat settings and ensure they are correct. It is also possible that the device requires recalibration.

Dust and debris can affect the temperature readings. If the device is registering incorrect temperatures, its performance will be erratic. You can use a soft cloth or a blower to get rid of grime on the thermostat.

If your HVAC system is still not working, it might be an issue with the thermostat’s location. When this device is in direct sunlight or near heating equipment, it may register wrong readings. Moving the device to a different location can fix the problem.

Last but not least, it could be that the thermostat is faulty and needs to be repaired or replaced. But first, check the batteries and replace them if necessary. If all that fails, you can consult an HVAC repair technician to troubleshoot and fix the problem. Anywhere in the Phoenix or Scottsdale areas, the skilled technicians from Champion Air would be happy to render assistance. An efficient thermostat is critical for the performance of your heating and cooling system.

Check for Airflow Obstructions

An imbalance in airflow is a common problem that affects the function of an HVAC system. Obstructions can prevent your HVAC unit from pulling or pushing air into the interior.

When there are airflow imbalances in your HVAC system, you will notice the following symptoms. You can consult our staff for prompt repair services.

  • Hot and cold spots throughout the house
  • The AC blowing out warm air
  • No air or low airflow from the vents
  • Whistling noises from the system

With air imbalances, clogged filters are among the most common culprits. By changing or cleaning your filter at least once a month, you can keep your HVAC system running efficiently.

You should also make a point of checking your outdoor unit for blockages. Leaves and debris can accumulate around the equipment. Such obstructions will overwork your system, cutting down its lifespan considerably.

The air in your home comes through the vents on the floor or ceiling. Blockages on the vents prevent air from circulating and regulating temperatures in your home. Consequently, you ought to make a point of checking all the vents and ensure there are no obstructions.

Switch Off the AC to Thaw Ice

One problem you may encounter during the summer is ice accumulating on the outdoor unit. Several factors can cause frost to develop. It could be airflow problems, a broken motor, grime on the evaporator coil or low refrigerant levels.

If there is frost on the outdoor unit in summer, the first step is to switch your AC off. Keep the fan on to let warm air pass over the condenser and thaw the ice. If your air conditioner is still not working after this, it might be an issue with airflow.

Check for airflow imbalances by removing obstructions around the vents. If the issue is a dirty coil or low refrigerant level, you will have to call an HVAC system professional. Only a certified technician has the skill and tools to clean coils and recharge the refrigerant safely.

A faulty motor will limit cool air from getting into the interior. You will have to replace the component to prevent further damage to the system. You can rely on the experts from Champion Air for a thorough assessment of your equipment.

Inspect Your Ductwork

You may also take the time to inspect your ductwork for blockages and leaks. If there are punctures in the air ducts, these can pull air in from the outside or allow conditioned air to escape. Dust and even toxic fumes could start circulating inside your home, or your utility bills could rise sharply.

One sign of faulty ductwork is when there are rooms that never seem to heat up sufficiently. If you turn on your furnace, the different parts of your home should heat up almost simultaneously. Your heating system will also have to work harder to keep the interior comfortable. Experts suggest that typical ductwork can lose between 20% and 40% of the energy it consumes.

One way to prevent leaks and blockages is to schedule duct cleaning and sealing regularly. Your ductwork has a lifespan of between 10 and 15 years. If your air ducts are more than 15 years old, you might need a replacement. You can talk to the staff at Champion Air about duct cleaning or sealing.

When to Call an HVAC Professional

You can address some problems by troubleshooting parts of your system. You can reset the thermostat and change the filter if your equipment is not functioning correctly. But when it comes to technical issues, it is best to leave the complicated repair tasks to a professional.

Your HVAC system is an essential investment for your home’s comfort and safety, and you can damage components by trying to repair it yourself. There is also the risk of electric shock or exposure to toxic refrigerant.

Additionally, fixing parts of your air conditioner can void your manufacturer’s warranty. That’s why you should always consult certified professionals with experience in fixing HVAC systems. Some components of your system can be expensive to replace. By upholding the status of your warranty, you can eliminate unnecessary repair costs.
